Hosting a retirement anniversary brunch at a country club is all about getting the timing right. Venues fill up early, so you need to lock in the space at least two months out before the best dates disappear.
A typical gathering runs around $1500 once you factor in food, drinks, and space rental. Securing your date early gives you the runway to spread out payments instead of taking one big hit all at once.
Keep in mind that 0% interest is a strict deadline, not free money. If you still have a balance on your Citi Simplicity® Credit Card when the 18 months end, the standard variable interest rate kicks in on whatever is left, making the event far more expensive.
